SMOKING-PEPE.

Specification forming part of Letters Patent No. 44,882, dated November l, 1564.

To` all whom it may concern,.-

Be it known that l, RUFUs Nonwoon, of Baltimore, county of Baltimore, and State of Maryland, have invented a new and Improved Tobacco-Pipe; and I do hereby declare that the following is a full, clear, and exact description thereof', reference b eing had te the accompanying drawings, making a part of this specification, in which-- Figure 1 is an external View of my improved pipe. Fig. 2 is a view showing the stem of the pipe partially withdrawn from the bowl. Fig. 3 is a diametrical section through Fig. 2. Fig. 4 is an enlarged sectional view ofthe stem of the pipe with its plunger. Fig. 5 is a perspective View of the tube which is inclosed within the stem of the pipe. Fig. is an end View of the pipe.

Similar letters ol' reference indicate corresponding parts in the several iigures.

This invention relates to certain novel improvements in smoking pipes, whereby a straight bowl and extensible or sliding stem are employed in conjunction with a piston or plunger, which latter is so constructed and applied to the stem of the pipe that it serves as a means for cleaning the bowl and forcing the ashes, 85e., therefrom during or after smoking; also, as a filtering and condensing kbok for absorbing the nicotine and purifying Vthe smoke in its passage to the mouth, as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

' In the accompanying drawings, A. represents the bowl of .the pipe, which may be made of any suitable substance, either of clay, wood, metal, or of any of the well-known substances commonly" employed in the manufacture of pipes. In the present case I have made the bowl A of wood and lined it inside with metal. The chamber of the bowl A is cylindrical and its rear end is partially closed, leaving a central pening for the passage of the stem B. If

desirable, there may be introduced into the end of the bowl a disk of cork or other equivale'nt substance, which will serve as a packing for the stem B and prevent the escape of smoke Vat this end of the bowl, but allow the stem to work freely through it.

The mouth of the bowl is provided with Aa hinged cover, a, which l is suitably perforated to admit air through it during the act of smoking.

The stem B of the pipe may be madecylin-y t snugly into the perforation through the rear end of the bowl, and yet be capable of sliding freely therethrough. This stem may be made of the same material as the bowl or of any other suitable material, and it may be made of the same length as the bowl or of any convenient length. For a portable pocketpipe the stem B should be made quite'short, so that it can be inclosed within the bowl; but for other forms of pipes long elastic or flexible tubes or stems may be substituted. @n that end of this stem B which works within the bowl A. a'eylindrical box, b, is applied in any suitable-manner, the diameter of whichequals that of the bore or chamber of the bowl A. This box has a .number of perforations through its forward end, as shown in Figs. 3, 4L, and 6, and it should be filled with some suitable absorbing substance, which will take up the juices and. purify the smoke, and which can be readily removed from said box and cleaned or replaced by a new piece.v Sponge v will be found to answer a very good purpose, and pumice may be used with the sponge to prevent the perforations through the forward end of the box from being closed up by the saturation and swelling of the latter. The smoke which is drawn through this box b enters a curved tube, e, which conducts it toward the mouth-piece C, thencev back again toward the box b, and finally outthrongh the mouth-piece, as will be understood by reference to Fig. 5. This peculiarly-curved tube, which is over three times the length of the stem B, within which it is inclosed serves two important purposes-viz., it cools the smoke by conducting it back and forth through the stem B, and it effeetually prevents the saliva from running into the box b and saturating the sponge with moisture, or it prevents any juices from escaping from the box b into the mouth.

The mouth-piece G may be made of amber or other suitable material, and attached to the stem by a screw or other fasteuin g. The box.b,which is formed on or applied to the stem of my pipe, serves not only the purpose of a filtering and' condensing' chamber for purifying the smoke,

2 messe chamber between the tobacco in the bowl and itself, which again assists in condensing the smoke and depriving it of its noxious propen ties.

packing the tobacco in the bowl and keeping italways in a condition for burning, thus ob- .viating the necessity for using the fingers for this purpose.

The plunger also serves as a means for Having thus described m5; invention, what I claim as new, and desire to secure byLetters Patent, is-

1. A' pipe which is constructed with a sliding stem, B, having a hollow plunger which serves as a liltering or condensing chamber, b, within the bowl of the pipe, substantially as described.

2. The combinationy of the chambered plunger b and tube c, substantially as and for the purpose described.
